The structure is visualized as a tetrahedron with four vertices of the first fcc lattice at (0,0,0), ( a /2,0,0), (0, a /2,0) and (0,0, a /2) and an additional atom added to the center of this tetrahedron. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals. The crystal lattice of silicon can be represented as two penetrating face centered cubic lattices (fcc) with the cube side a 0.543nm as portrayed in Figure 3.1. Please note that the elements do not show their natural relation towards each other as in the Periodic system. The first chemical element is Hydrogen and the last is Ununoctium. The chemical elements ofįor chemistry students and teachers: The tabular chart on the right is arranged by Atomic number. Germanium is a relatively fragile white or silvery metal which cannot react (or reacts weakly) with air, water, acids except nitric acid. This list contains the 118 elements of chemistry. With the atomic number 32 Ge is a member of the group of crystallogens. 14 electrons (white) occupy available electron shells (rings). The nucleus consists of 14 protons (red) and 14 neutrons (orange).

Silicon Si Element 14 Mass Number: 28 Atomic weight: 28. Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of silicon-28 (atomic number: 14), the most common isotope of this element.Since mass number is defined as the sum of the number of protons and the number of neutrons the atom has in its nucleus, it follows that you can write. Plant Inspection & Process Optimalisation In your case, the name boron-11 is used to designate an isotope of boron that has a mass number equal to 11.
